Abstract
1. The half-life of Th C′ was determined by a new method of coincidence technique.2. Previous investigators have recognized difficulties in regard to this investigation. These were: (a) random delays in the counters; (b) coincidences due to other disintegrations; (c) possibility of difference in delays in recording α- and β-particles. In this investigation the difficulties arising from these effects have been overcome.3. From this type of experiment it is possible to determine the order in which the particles are emitted.4. It would appear that the time of breakdown of a counter depends slightly upon the magnitude of the initialionization.5. The value for the half-life of Th C′ was found to be 3.0 ± 0.15 × 10−7 sec.
